基于现场调查的地下工程人员热感觉分析
Thermal sensation analysis of underground engineering occupants based on field tests and questionnaires
摘要：
通过对影响地下工程热环境的特殊因素进行分析，探讨了地下工程内人员热感觉变化的主要原因。对全国32个典型城市地下工程内部进行了热环境测试和人员热感觉问卷调查，分析了地下工程平均辐射温度对人员热感觉变化的影响，对比分析了人员的实际平均热感觉指标AMTS和预计平均热感觉指数PMV。结果显示：地下工程内温度较低时，人员的实际冷感更强烈；而温度较高时，AMTS比PMV略小。对全国不同地域的热中性温度与地温进行了回归分析，得到了地下工程的热中性温度模型和可接受的温度范围。
Abstract：
Analyses the special factors affecting the thermal environment in underground engineering, and studies the main reasons for the occupants thermal sensation change. Elaborates a specific thermal sensation questionnaire and field tests for investigation on 32 underground engineering projects in different areas. Analyses the influence of the mean radiant temperature on the occupants thermal sensation change, and compares the actual mean thermal sensation (AMTS) values of occupants with the predicted mean vote (PMV) values. The results show that the occupants have the lower value of AMTS in the cooler side but exhibit higher warmth tolerance and adaptivity in warmer side. Carries out the regression analysis on the thermal neutral temperature and ground temperature in different regions, and develops the thermal neutral temperature models and thermal acceptable temperature ranges for underground engineering.
